16 Global Operational Data Link Document (GOLD) (xv) FOREWORD. 1. Historical background 1.1 The Global Operational Data Link Document (GOLD) is the result of the progressive evolution of the ICAO Asia-Pacific (APAC) Initial Future Air Navigation System (FANS 1/A) Operations Manual, the North Atlantic (NAT) Guidance Material for ATS Data Link Services in North Atlantic Airspace and the Eurocontrol LINK2000+ Guidance Material for the aeronautical telecommunication network baseline 1 (). 1.2 Each of these founding documents provided guidance on a regional basis. However, in recognition of the need to provide globally harmonized guidance on data link operations, the GOLD, First Edition, merging initially the APAC and NAT guidance material, was adopted by the APAC and NAT Regions in The Second Edition of the GOLD enabled integration of the LINK2000+ guidance material. 1.3 The GOLD addresses data link service provision, operator readiness, controller and flight crew procedures, performance-based specifications and post-implementation monitoring and analysis. 2. Scope and purpose 2.1 The GOLD provides guidance and information concerning data link operations and is intended to facilitate the uniform application of Standards and Recommended Practices contained in Annex 2 Rules of the Air, Annex 10 Aeronautical Telecommunications and Annex 11 Air Traffic Services, the provisions in the Procedures for Air Navigation Services Air Traffic Management (PANS-ATM, Doc 4444) and, when necessary, the Regional Supplementary Procedures (Doc 7030). 2.2 This guidance material is intended to improve safety and maximize operational benefits by promoting seamless and interoperable data link operations throughout the world. This edition applies to the FANS 1/A and data link operations using automatic dependent surveillance contract (ADS-C), controller-pilot data link communications (CPDLC) and the flight management computer waypoint position reporting (FMC WPR). Additional guidance is provided on the use of automatic dependent surveillance broadcast (ADS-B) in-trail procedures (ITP). It also addresses the performance of the data link applications taking into consideration the transmission media used by those applications. 2.3 The following personnel and organizations should be familiar with relevant aspects of its contents: regulators, airspace planners, aircraft operators, dispatchers, air navigation service providers (ANSPs), aeronautical stations, communication service providers (CSPs), satellite service providers (SSPs) and radio operators, training organizations, regional/state monitoring agencies, automation specialists at centers and radio facilities, and aircraft manufacturers and equipment suppliers. 2.4 The guidance will support the following activities: a) The States roles and responsibilities in relation to the following: 1) Safety regulatory oversight of air navigation services; 2) Operational authorizations, flight crew training and qualification; and 3) Design approval of aircraft data link systems. GOLD (xv) Second Edition 26 April 2013

17 (xvi) Global Operational Data Link Document (GOLD) b) The development of agreements and/or contractual arrangements between ANSPs and aircraft operators and their respective communication service providers; c) The development of operational procedures; and d) Operational monitoring, analysis, and exchange of operational data among regions, States, and communication service providers. 3. Status This guidance is approved and maintained by the respective participating PIRGs and has a status of an ICAO regional guidance material. It contains material that may eventually become Standards and Recommended Practices (SARPs) or PANS provisions when it has reached the maturity and stability necessary for adoption or approval. It also comprises material prepared as an amplification of the basic principles in the corresponding SARPs, and designed particularly to assist the user in the application of the SARPs and PANS. 4. Implementation With a view of facilitating implementation of the provisions herein by States, this guidance material has been prepared using language that permits direct use by all users. 5.

Changes to the document This document is maintained as a regional document in coordination with all ICAO planning and implementation regional groups (PIRGs) providing data link services within their region. Each participating PIRG establishes a mechanism for submitting and administering change proposals. Change proposals (CPs) can be submitted by any stakeholder participating in data link operations. The stakeholder should submit a Change Proposal to their ICAO regional office (see Appendix E). The ICAO regional office will coordinate the change proposal within its own region, other regions, and ICAO HQ, to determine the acceptability of the change proposal. Once the ICAO regional office has completed coordination and the participating PIRGs accept the change proposal, the change is concluded by each of the PIRGs.

CPDLC message. Information exchanged between an airborne application and its ground counterpart. A CPDLC message consists of a single message element or a combination of message elements conveyed in a single transmission by the initiator. Note. The abbreviated term message is commonly used to refer to a CPDLC message. CPDLC message element. A component of a message. A message element is defined for specific uses (e.g. vertical clearance, route modification). A free text message element provides additional capability. Note. The abbreviated term message element is commonly used to refer to a CPDLC message element. Current data authority (CDA).

25 1-6 Global Operational Data Link Document (GOLD) Term Dynamic airborne re-route procedure (DARP). The procedure for executing a re-route clearance initiated by a request from AOC. Filed flight plan. (See flight plan). Flight crew member. A person authorized by the appropriate authority charged with duties essential to the operations of an aircraft on the flight deck during a flight duty period. Flight identification. A group of numbers, which is usually associated with an ICAO designator for an aircraft operating agency, to identify the aircraft in Item 7 of the flight plan. Flight information region (FIR). An airspace of defined dimensions within which flight information service and alerting service are provided. (ICAO) Flight level (FL). A surface of constant atmospheric pressure which is related to a specific pressure datum, hectopascals (hpa), and is separated from other such surfaces by specific pressure intervals. (ICAO) Note 1. A pressure type altimeter calibrated in accordance with the Standard Atmosphere: a) when set to a QNH altimeter setting, will indicate altitude; b) when set to QFE altimeter setting, will indicate height above the QFE reference datum; c) when set to a pressure of hpa, may be used to indicate flight levels. Note 2. The terms height and altitude, used in Note 1 above, indicate altimetric rather than geometric heights and altitudes. Flight plan. Specified information provided to air traffic services units, relative to an intended flight or portion of a flight of an aircraft. (ICAO) A flight plan can take several forms, such as: Current flight plan (CPL). The flight plan, including changes, if any, brought about by subsequent clearances. (ICAO) Note 1. When the word message is used as a suffix to this term, it denotes the content and format of the current flight plan data sent from one unit to another. Filed flight plan (FPL). The flight plan as filed with an ATS unit by the pilot or a designated representative, without any subsequent changes. (ICAO) Note 2. When the word message is used as a suffix to this term, it denotes the content and format of the filed flight plan data as transmitted. Aircraft active flight plan.
